They just dropped the latest single, “American Horror,” off their upcoming EP, Real Hair, produced by Paul Q. Kolderie, whose credits are a who’s who of college rock/grunge gods: Pixies, Radiohead, Dinosaur Jr, and Hole. That should be enough to fuel those “OMG, the ‘90s” exclamations that accompany every one of their releases, but Speedy Ortiz are no tribute act; if they echo those 120 Minutes all-stars, it’s in spirit more than practice. No affectation here. Just listen to the foregrounded, full-hearted guitar-and-drums crunch of “American Horror” and the heart-on-sleeve lyricism of underground hero/Creative Writing MFA candidate Sadie Dupuis, and get excited for the next dose.
